I put "believe" specifically because I knew I didn't know much on the topic and they were a country I knew used a lot. I was very intentionally signalling my lack of certainty about that sentence. A simple correction rather than an assumption of....whatever the hell it is you are vaguely accusing me of would have been much more helpful.
That being said, thanks for the heads up! However, it really just strengthens my point that even more countries are using desal and not mining the brine.
